CVSS: 5.3EPSS: 0%CPEs: 32EXPL: 0CVE-2015-8629 – krb5: xdr_nullstring() doesn't check for terminating null character
https://notcve.org/view.php?id=CVE-2015-8629
The xdr_nullstring function in lib/kadm5/kadm_rpc_xdr.c in kadmind in MIT Kerberos 5 (aka krb5) before 1.13.4 and 1.14.x before 1.14.1 does not verify whether '\0' characters exist as expected, which allows remote authenticated users to obtain sensitive information or cause a denial of service (out-of-bounds read) via a crafted string. La función xdr_nullstring en lib/kadm5/kadm_rpc_xdr.c en kadmind in MIT Kerberos 5 (también conocido como krb5) en versiones anteriores a 1.13.4 y 1.14.x en versiones anteriores a 1.14.1 no verifica si existen caracteres '\0' según lo esperado, lo que permite a usuarios remotos autenticados obtener información sensible o causar una denegación de servicio (lectura fuera de rango) a través de una cadena manipulada. An out-of-bounds read flaw was found in the kadmind service of MIT Kerberos. An authenticated attacker could send a maliciously crafted message to force kadmind to read beyond the end of allocated memory, and write the memory contents to the KDC database if the attacker has write permission, leading to information disclosure. • http://krbdev.mit.edu/rt/Ticket/Display.html?id=8341 http://lists.opensuse.org/opensuse-updates/2016-02/msg00059.html http://lists.opensuse.org/opensuse-updates/2016-02/msg00110.html http://rhn.redhat.com/errata/RHSA-2016-0493.html http://rhn.redhat.com/errata/RHSA-2016-0532.html http://www.debian.org/security/2016/dsa-3466 http://www.oracle.com/technetwork/topics/security/bulletinapr2016-2952098.html http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html htt • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
CVSS: 6.5EPSS: 6%CPEs: 30EXPL: 0CVE-2015-8631 – krb5: Memory leak caused by supplying a null principal name in request
https://notcve.org/view.php?id=CVE-2015-8631
Multiple memory leaks in kadmin/server/server_stubs.c in kadmind in MIT Kerberos 5 (aka krb5) before 1.13.4 and 1.14.x before 1.14.1 allow remote authenticated users to cause a denial of service (memory consumption) via a request specifying a NULL principal name. Múltiples pérdidas de memoria en kadmin/server/server_stubs.c en kadmind en MIT Kerberos 5 (también conocido como krb5) en versiones anteriores a 1.13.4 y 1.14.x en versiones anteriores a 1.14.1 permiten a usuarios remotos autenticados causar una denegación de servicio (consumo de memoria) a través de una solicitud especificando un nombre principal NULL. A memory leak flaw was found in the krb5_unparse_name() function of the MIT Kerberos kadmind service. An authenticated attacker could repeatedly send specially crafted requests to the server, which could cause the server to consume large amounts of memory resources, ultimately leading to a denial of service due to memory exhaustion. • http://krbdev.mit.edu/rt/Ticket/Display.html?id=8343 http://lists.opensuse.org/opensuse-updates/2016-02/msg00059.html http://lists.opensuse.org/opensuse-updates/2016-02/msg00110.html http://rhn.redhat.com/errata/RHSA-2016-0493.html http://rhn.redhat.com/errata/RHSA-2016-0532.html http://www.debian.org/security/2016/dsa-3466 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html http://www.securitytracker.com/id/1034916 https://github.com/krb5/krb5&# • CWE-401: Missing Release of Memory after Effective Lifetime CWE-772: Missing Release of Resource after Effective Lifetime •
